IMPROVEMENT IN WATER-CLEANSING APPARATUS.

Specification forming part oi' Letters Patent No. 146,940, dated January27, 1874; application filed June 11, 1873.

To all fwhom it may concern:

Be it known that I, MnLcHroR NOLDEN, of Frankfort-on-the-Main, Empire ofGermany, have invented a new and Improved fater- Cleansing Apparatus;and I do hereby declare the following to be a full, clear, and exactdescription thereof, which will enable those skilled in the art to makeand use the saine, reference being had to the accompanying drawingforming part of this specification, in which drawing- Figure 1represents a vertical central section of this apparatus. Fig. 2 is atransverse section thereof, taken inv the plane x x, Fig. 1.

. Fig. 3 is a horizontal section in the plane g/ y,

Fig. l. Fig. et is a front view end of the same. Similar lettersindicate corresponding` parts. This invention relates to an apparatus inwhich thewater is subjected to two separate and consecutive cleansingoperations, rst being thoroughly commingled or infused with steam, andthen being subjected to the action of suitable chemicals, whereby allforeign matters contained in the water are precipitated and collected inthe bottom of the apparatus, and the water ows out freed and devoid ofall impurities.

My invention consists in the arrangement, in a water-cleansingapparatus, of a horizontal partition or false bottom forming tworeservoirs or chambers, in each of which the water is subjected to aseparate cleansing operation, said chambers connnunicating with eachother by suitable openings. It further consists in the arrangement ofawater-vessel in the steamspace of the upper cleansing-chamber, whichacts in conjunction with a bucket-wheel mounted in said steam-chamber,the water in the vessed being heated to a high temperature by means ofsteam, while the bucket-wheel is operated by the iiow of water from thesaid water-vessel, so that the water is made to serve as a motive powerduring the operation of cleansing. It consists further in thearrangement of a series of vertical partitions in the lowercleansing-chamber, each alternate partition terminating, respectively, ashort distance from the top and bottom of said chamber, thus forming acommunication between the spaces formed by the said partitions andproducing a circulation of the water in said l chamber. My inventionconsists further in the arrangement of a box or vessel containing aliquid chemical on the outside of the lower cleansing-chamber, theliquid iowin g from said vessel into a tubular sha-ft that eX- tends tothe inside of my apparatus, in such a manner that, when a revolvingmotion is imparted to said shaft, the liquid is taken up and passed intothe lower cleansing-chamber.

In the drawing, the letter A designates the outer shell or case of myapparatus in which is arranged a horizontal partition, B, that dividesit intotwo separate chambers or reservoirs, C D.` Steam is let into thechamber C through a pipe, a, in the side of said chamber. In thissteam-cham ber C the water is subjected to the rst cleansing operation,which consists in thoroughly infusing the water with steam, when it soonreaches a high temperature, and all alkaline matter contained in thewater is precipitated and falls to the bottom, where it in the side ofthe apparatus, Fig. 4.

Of course, in the above operation the greater part of the steam iscondensed and mixed with thewater, but any part remaining uncondensedcan pass out through a pipe, b, that issues from chamber through theopenings h i in its iioor.

In the steam-space of the chamber G I place an open water-vessel, E,free ofthe sides of said chamber, being supported by angle-irons c. (SeeFig. 2.) W'ater is let into said vessel by means of a pipe, ci. In thisvessel E the water soon becomes heated to a high temperature and thelime or other alkaline matters are precipitated. The water leaving thevessel E by means ofthe spout c, iiows on the buckets of a wheel, F,which is mounted on a shaft, Gr, at one end of the steam-chamber, onwhich shaft is also mounted a pulley, j", and the water, causing saidwheel to revolve, forms a motive power for my apparatus at the same timethat it is being cleaned. The water in passing' from the vessel E on thebucket-wheel F, and

comes more thoroughly infused and commingled with the steam, and asecond and more thorough precipitation of alkaline matter takes place.

In thc partition B arc openings provided collects and is removed throughport-holes g the lower chamber D, the steam entering said Y thence tothe tloor of the steam-chamber, be-

with pipes It 1', which form a conununication between the two chambers(l D, and through these pipes the water passes from the steamchamber Cinto the lower chamber D, wher it is subjected to the second cleansingoperation which is, by means ot' suitable chemicals, by which theforeign substances chemically mixed with the water are precipitated,and, as in the steam-chamber, collect on the bottom a u d are removedthrough port-holes an d pipes 7.1. The chemical solution is contained ina box or vessel, Il, on the outside of the chamber D, said vessel havinga pan or dish, l, arranged ou one end thereo't', into which the liquidflows through a small hole in the side ot said vessel, whence it isdipped up by a spiral or coiled pipe, J, which has a revolving motion,and which leads into and is mounted on. a tubular shaft, K, whichextends to the inside of the chamber D. On the tubular shaft K is alsomounted a pulley, l, which is connected, by means of a belt, m, with thepulley j' of the l wheel-shaft Gr, and thereby a revolving motion isimparted to the coil J, when it draws off and feeds the liquid into theshaft K, as already stated. The tubular shaft K has its bearing inajournal, L, in the side wall oi" the chamber lr), and it is alsosupported by vertical partit-ions M M M M M arranged within saidchamber, and these partitions communica-te with each other by alternateopenings on top and bottom of the same. The quantity of liquid to bedipped up and fed into the ehan1 ber D is regulated by raising andlowering` the dish I, which has a screw-support, N.

It' the water contains other substances besides plaster-of-paris, whichare to be precipitated in a third cleansing, and whereby a spe@ cialsolution of chemicals is necessary, then a second vessel, H, containin gthe solution, such as carbonate of soda and chloride of barium,

and a second feeding-rupe turned by a belt i'rom the'wheel-shait G, arearranged next to the iirst one, which passes the solution into thefirst, second, &c., part of the chamber D. The water has time andopportunity to precipitate these substances in its circulation throughthe vertical partitions M. rlhe lighter substances, as magnesia, soinjurious to steamboilers, are separated, being retained floating on thesurface of the water between the partitions, which alternately reachabove the waterlevel. After having passed through the two operations ofcleansing, the water becomes nearly or entirely cold, and it flows outof the apparatus through au outlet or overtlow pipe, n.

lt will be observed that it is invariably by its overiow that the waterpasses from the water-vessel into the steam-chamber, and thence into thelower chamber D, as also in emerging from the apparatus, and by thesemeans there is no danger of any sediment or impurities passing off withit.

In cleaning the apparatus, any water or sediment remaining on the floorofthe steam-chamber C may be cleaned out through the portholes g, asalready stated; or it is allowed to drop down into the lower chamber Dby removing the plugs o o in the partition B, and from there it is thencleaned out through the pipesj and holes 7;.

The great advantage that this apparatus oil fers is that, besides beingable to make use ot' the exhaust steam ot steamboilers-also, by acontinuedworkingoftheapparatus-4x11foreigii substances mechanically andchemically combined with the water can be separated in a most rationaland cheap manner.

W'hat I claim as new, and desire to secure by Letters Patent, is-

1. The arrangement, in a Awatereleansing apparatus, of a horizontalpartition or falsix bottom, forming reservoirs or chambers (l D, in eachot which the water is subjected to a separate cleansing' operation,substantially as described.

2. The water-vessel E, arranged in the steam space of t-he uppercleansing-chamber C, in combination with a bucket-wheel, F, arranged inrespect to each other, substantially as de scribed, for the purposespecified.

3. The arrangement of a box or vessel, ll', containing a chemicalsolution on the outside of the chambers D, the solution iiowing fromsaid vessel into a pan, from which it is dipped up by a coiled pipe andfed into a tubular shaft that extends to the inside ofthe chamber D,substantially as and for the purpose speci tied.

4. The combination of thc partitions M hl with the pipe K anddipping-pipe J, substantially as described, for the object specified.

5. The adjustable dish I and chemical-chamber H, in combination with thedipping-pipe J, pipe K, and partitions M M, substantially as described,tor the purpose specified.
